Abstract
A component includes a transmission arrangement for transmitting a force between an actuator and a control valve. The transmission arrangement includes a post that is associated with the actuator. The control valve is displaceable to an open position from a closed position when an opening force is applied to the control valve that is greater than a closing force provided to the control valve. The transmission arrangement is disposed in the component between the post and the control valve actuator and arranged to mechanically transmit by physical contact an actuator force from the post to the control valve when the post begins to travel towards the extended stroke position, and hydraulically amplify the actuator stroke between the post and the control valve when the post travels from the retracted stroke position to the extended stroke position.
